DARPA's Distributed Agile Submarine Hunting (DASH) Program has tested two complementary prototype systems as part of its Phase 2 development effort. The prototypes demonstrated functional sonar, communications and mobility ...

They have looked at 140,000 images, identified 42,000 scallops on the bottom of the ocean and donated countless hours of their time—and the scientists that they are assisting don't even know who they are.

Since the plate tectonics revolution of the 1960s, scientists have known that new seafloor is created throughout the major ocean basins at linear chains of volcanoes known as mid-ocean ridges. But where exactly does the erupted ...

How do bone-eating worms reproduce? A new study by Norio Miyamoto and colleagues from the Japan Agency for Marine-Earth Science and Technology sheds light on this question through a detailed observation of the postembryonic ...

A collaboration between the National Oceanography Centre (NOC) and the University of Southampton is to develop an instrument capable of simulating the high pressures and low temperatures needed to create hydrate in sediment ...

(Phys.org)—Fungi living beneath the seafloor are widespread in ocean environments around the world, according to a new paper by scientists at the University of Delaware and Woods Hole Oceanographic Institution.

Seabed

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean. At the bottom of the continental slope is the continental rise, which is caused by sediment cascading down the continental slope. The seabed has been explored by submersibles such as Alvin and, to some extent, scuba divers with special apparatuses. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.
